This report is a fairly outdated and probably expensive UN report stating the obvious.
We already knew these data from a UK report published over a year ago which shows how Britons throw away 30 percent of the food they buy, even when it is perfectly edible. But so what ?
When we go to the developing countries, where people are presumably poorer than in Britain and therefore likely to reject less of a prime commodity like food, well (guess who ?), UNEP in a report in 2005 tells us that organic (including food) waste accounts for up to 70 percent of urban waste.
Greenpeace reported on fisheries by-catch over a decade ago, demonstrating how many millions of tonnes are wasted annually.
So what has the new UNEP report added ?
What it could have said was : if we can correctly manage and capture the potential in food waste we could:
A) produce energy
B) produce fertilisers
C) reduce CO2 emissions
Until food is so expensive that we cannot afford to waste it all the rest is just talk. The fact is food is too cheap and this comes down to how we obscenely subsidise food production, especially in the rich countries. But that is another question waste managers cannot ask.
